If you ever used Seeed's Grove products, you will fell in love with this kind of modules. With this kind of ports, you can say goodbye to jumper wire and soldering work, and you can make more powerful applications with those functional modules.

If you compare V1.0 and V2.0, you can notice that there are six pins and two jumper caps on bottom-right corner. These pins are used to switch phone connector protocol. As you set tiny jumper(both) to left-four pin, protocol OMTP is used. As you set tiny jumper(both) to right-four pin (as preceded figure shows), protocol CTIA is used. As following figures show:
